as often as i can, i stay in/on the water till exhaustion. several times i've found myself slipping much more towards the day's end than at the beginning. when i do get the rare chance to venture all day, i make sure when i'm approaching the end to slow my pace (which i don't always do).

also, i don't if anybody else has had this experience but i've spoken with a few friends and some of them knew it exactly. On occasion, i've found myself on some trail or creek and just had to keep going, no matter what. the feeling was like some primal urge to just go as far as i could and then go further. a very irrational and potentially dangerous situation. as scary as it's arrival is, once that feeling hits only rarely have i been able to resist it.
